Most integration proposals price a build and go quiet about everything around it — who decides the business rules, who owns the error queue, what happens when SAP Business One is upgraded. Twopir Consulting scopes all three service lines explicitly: the work to design and build it, the work to fit it to rules that keep changing, and the work to keep it running. You should know which of those you are buying before you sign.
Trusted by 500+ organizations — including distributors, manufacturers and field-service businesses running HubSpot in front of an ERP with Twopir Consulting.
Service Lines and Platforms
These are the six situations that bring companies to this page. Most are not technical failures — they are scope and ownership failures that show up later as technical ones.
A fixed number against a feature list, with the business rules still undecided. The rules are where the cost actually lives, so the number moves the moment discovery starts — and the conversation turns into a change-request argument.
The CRM partner points at the ERP partner and the ERP partner points back. Every question that lands exactly on the integration boundary takes a week and a meeting to answer, and the questions that matter all land there.
The build was signed off and the team moved on. Six weeks later a handful of orders never reached SAP Business One, and nobody noticed until a customer asked where their delivery was.
A SAP Business One upgrade, a credential rotation or a HubSpot property rename takes the integration down. There is no runbook, no test environment and no named person, so recovery is improvised under pressure.
It works, mostly. No mapping document, no owner, no record of why a rule exists. Every change is a risk because nobody can say what else depends on the thing being changed.
A packaged app handles the standard objects, and the remaining twenty per cent is a person with a spreadsheet. That twenty per cent is usually where the margin and the customer experience actually live.
Implementation, configuration and run are separate services with separate costs. Knowing which one you are buying is the single most useful thing you can establish before talking to anybody.
SAP Business One HubSpot integration services cover three different kinds of work, and conflating them is how engagements go wrong. Implementation is designing and building an integration that does not exist yet. Configuration and extension is making something that already exists — a packaged connector, an iPaaS recipe, an inherited build — fit rules it was not designed for. Run is owning it afterwards: the error queue, the credentials, the regression tests, the upgrade path.
Three different buyers ask for these. A company connecting HubSpot to SAP Business One for the first time needs the first. A company whose connector covers the standard objects but not the approval rule that matters needs the second. A company whose integration works but has no owner needs the third, and usually needs it urgently.
Twopir Consulting offers all three, separately or together, and we will tell you which one you actually need. We help growing and mid-market companies solve complex CRM, integration, and business system challenges. If the honest answer is that your existing connector can be configured to do what you want, we will say so — that is a smaller engagement than a rebuild and a better outcome for you.
Bought separately or together. The boundary between the first two is the question of whether the thing already exists; the boundary between build and run is go-live.
Designing and building an integration that does not exist yet — the architecture, the mapping, the build and the cutover.
Making what you already have fit the rules it was not designed for — without throwing away work that is doing its job.
Owning the integration after go-live, which is the service line most proposals leave out and most failures trace back to.
Published deliberately, because the items in the “your side” column are the usual cause of a slipped go-live. Knowing them now is worth more than a lower headline number.
| Work | Owner | What it covers | In a Twopir engagement |
|---|---|---|---|
| Integration architecture and design | Twopir | Route selection, object and field mapping, business rules, error strategy. | Included |
| Business rule decisions | You, facilitated by Twopir | When an order is created, who owns pricing, how a customer is matched, what happens on rejection. We run the session and write it down; the decisions are yours. | Joint |
| HubSpot-side configuration | Twopir | Properties, custom objects, pipelines, workflows and the private app scoped to the mapping. | Included |
| Integration build and testing | Twopir | The middleware or connector configuration, tested against a SAP Business One test company before it touches production. | Included |
| SAP Business One environment readiness | Your SAP partner or IT | Service Layer enabled and reachable, licensing, an integration user, network access to the agreed addresses, a usable test company database. | Your side |
| Changes inside SAP Business One | Your SAP partner | User-defined fields and objects, approval procedures, document settings. We specify exactly what is needed; your SAP partner applies it. | Your side |
| Data cleanup before go-live | Joint | Duplicate companies, missing tax IDs, items without a usable code. We identify it and can do the work; the decisions about which record survives are yours. | Joint |
| Monitoring, replay and support | Twopir, or handed over | Error queue, alerting, reconciliation and the runbook. | Choose |

Different situations want different shapes. An assessment is often the right first purchase even when a build is the eventual answer.
| Model | What it is | Fits when | What you get |
|---|---|---|---|
| Integration assessment | A fixed-scope review of an integration you already have, or of your readiness to build one. | You have a connector that is not behaving, or an inherited build nobody can explain. | A findings document: what it does, where it fails, what it would take to fix, and whether a rebuild is warranted. |
| Fixed-scope build | Design and delivery of an agreed set of flows, priced after the mapping document is signed rather than before. | The scope is genuinely knowable — a defined set of objects and directions. | A tested, documented integration, plus the runbook and the handover. |
| Phased programme | A first phase that proves the hardest flow, then further phases against a roadmap. | The full scope is large, or the business wants value before committing to all of it. | Working flows at the end of each phase, not at the end of the programme. |
| Managed run | Ongoing ownership of a live integration: monitoring, replay, changes and regression testing after platform updates. | You want the integration owned by people who know it, rather than by whoever is available. | A named owner, an agreed response commitment, and a monthly view of what failed and why. |

Four steps, and you can stop after any of them. The assessment output is yours whether or not we build it. The delivery detail is on the implementation page.
A working conversation, not a pitch. We want the process you run, the systems you have, and the thing that made you start looking.
A fixed-scope review of your environment, your existing integration if there is one, and the data you would be synchronising.
The mapping and rules session, written up, and a proposal priced against that document rather than against a guess.
Delivery against the signed scope, then either a handover with the runbook or an ongoing managed run.
The difference between an integration that works in month one and one that still works in month eighteen is almost entirely in these four.
The mapping and rules document is the contract. Anything not in it is a change, and both sides can see that clearly instead of arguing about intent.
The CRM architecture and the ERP interface are designed by the same team, so questions that sit exactly on the boundary get answered rather than forwarded.
Either us under a managed run, or your team with the runbook, monitoring and documentation they need. What we will not do is leave it unowned.
Price lists move, warehouses are added, SAP Business One is upgraded. The design assumes change rather than treating each one as an incident.
These are how the service lines are typically combined, not client metrics — we publish numbers only where a specific engagement has measured them. The case study beside them is real and linked.
A connector that covers standard objects is usually worth keeping. We assess what it does, what it cannot reach, and whether the gap is configuration, a missing cross-reference or a genuine product limit — before anybody proposes replacing it.
The connector keeps the standard objects and directions. A small custom service handles the approval gate, the multi-company rule or the object it does not carry. Two components, one mapping document, one owner.
Monitoring, alerting that names the failing record, replay under an agreed procedure, and a periodic reconciliation that the two systems still agree at the count level.
Before a SAP Business One upgrade or a significant HubSpot change, the integration is re-tested against the test company so the first evidence of a problem is not a customer's missing delivery.
A quote-to-order process rebuilt across CPQ and the systems around it. Different platform pair, the same engagement shape: assess first, write the scope down, build against it, then own what was built.
We work with growing, mid-market, and enterprise organizations that need help with complex CRM implementations, integrations, and business system challenges. SAP Business One sits where a CRM mistake becomes an accounting mistake, which is why the engagement is shaped differently from a CRM project.
Field mapping is a day. Deciding which system owns pricing, when an order may be created and what happens when SAP refuses it is the actual work, and it happens before the build rather than during it.
If your existing connector can be configured to do what you want, that is a smaller engagement and a better outcome. We would rather say so than sell a rebuild you did not need.
As a HubSpot Partner with an integration practice, we architect the CRM and the ERP interface together, so nothing falls into the gap between two vendors.
Monitoring, replay, reconciliation and regression testing are priced and staffed, because an unowned integration degrades silently and expensively.
We work with growing, mid-market, and enterprise organizations that need help with complex CRM implementations, integrations, and business system challenges. The engagement shape changes with that — a phased programme suits a large scope, a fixed-scope build suits a clear one — but the discipline does not.
Including the cost question, answered as honestly as it can be answered before a mapping document exists.
Honestly: not knowable before the mapping document exists, and any firm number offered earlier is a guess wearing a suit. The cost driver is not the number of objects, it is the number of business rules and the state of your data.
What we do instead is run a fixed-scope assessment, produce the mapping and rules document, and price the build against that. You get a real number and a written scope at the same time, and you are free to take that document elsewhere.
We start by assessing whether it needs replacing at all, because usually it does not. A packaged app that handles standard objects reliably is doing useful work; the gap is normally a rule it was never designed to carry.
The common outcome is to keep the connector for what it does well and build a small custom layer beside it for the rest. One mapping document covers both, so there is still a single place that describes how the two systems relate.
A SAP Business One environment we can reach — Service Layer enabled and licensed, an integration user, network access authorised for the agreed addresses, and a test company database that resembles production.
Also people. Someone who can decide business rules, someone who knows the ERP configuration, and someone who owns the HubSpot portal. The decisions are yours; we facilitate them and write them down. The scope table above sets out who does what.
Yes, and it is usually the right arrangement. They know your ERP configuration, your localization and your history with it; that knowledge is not something an integration partner should try to replace.
We specify precisely what is needed on the SAP side — the user-defined fields, the integration user's permissions, the document settings — and they apply it. The boundary is written into the scope document so nothing sits between us.
Monitoring of the integration queue with alerts that name the failing record rather than just reporting that something failed. Replay of failed transactions under an agreed procedure. Periodic reconciliation that the two systems still agree at the count level. Regression testing after SAP Business One or HubSpot changes.
It also includes a named owner and an agreed response commitment, so there is a person to contact rather than a queue to join.
A discovery call is usually within the week. An assessment typically starts within two to three weeks of agreeing scope, depending on the current schedule.
The realistic constraint is rarely our availability — it is getting Service Layer access authorised and a usable test company in place on your side. We raise that in the first call precisely because it is the most common cause of delay.
Yes. Twopir Consulting delivers across the US, Canada, the UK, the UAE, Australia and New Zealand, with teams in Pune, India and New Haven, Connecticut.
For SAP Business One specifically, localization matters: tax handling, document numbering and statutory fields differ by country, and those differences belong in the mapping document rather than being discovered during user acceptance testing.
Four companion pages. This one covers how the work is bought; the others cover how it is designed, delivered and extended.
Bring the integration you have, or the one you are about to buy. We will tell you whether this is an implementation, a configuration problem or an ownership problem — and what each one would realistically cost you.
