A single customer needs one integration.
It shouldn’t cost you a roadmap slot.
We build the customer-specific integration a deal depends on — into their ERP, their CRM, their homegrown system — without it becoming a permanent feature your team has to own, document and maintain forever.

The deal is worth it. The roadmap slot isn’t.
They are waiting on you, and they are watching how long you take. Your engineers are committed to the current sprint, so the earliest real start date is next quarter. That is too late. The deal goes quiet, or someone else gets it.
The contract is signed pending a connection to a system you have never sold into — an on-prem ECC instance, a homegrown warehouse tool, a regional payroll platform. Building it as a product feature would be absurd. Losing the deal would be worse.
The moment an integration enters your product it needs docs, support runbooks, upgrade testing, and an owner. That is the right trade-off for a system ten customers use. For a single customer it is a tax you pay every quarter for a decision you made once.
You keep the deal; your engineers keep the sprint. Weighing it up? Read Build in-house or outsource.
Not just a data pipe.
Integrations with logic built in.
What every one-off integration includes.
One-off build, or product connector?
Build it one-off when…
A single customer has asked. The system is unusual, on-prem, regional, or homegrown. Their environment is heavily customized. The deal has a date on it. Nobody on your roadmap committee wants to own this system for the next three years.
You are on the right page.
Build a connector when…
Two or more customers have asked, or sales keeps running into the same system in deals. It belongs on your integrations page. You want customers to switch it on themselves and you are ready to own it as a feature.
From blocked deal to live integration.
Scope with you and the customer
A call with your team, then one with their IT if useful. We map their environment, their customizations, their access rules. Fixed quote and a date before anything starts.
Build against their sandbox
We work in your repo, in your conventions. Weekly demos you can forward to the customer, direct Slack access, no status decks.
Go live and hand over
Deployed in your infrastructure, joint-tested with the customer, documented for your support team as first responder. Eight hours of post-launch support.
Who should build the integration this deal needs?
| Your own team | Contractor | The customer’s integrator | Inovaflow | |
|---|---|---|---|---|
| Start date | Next sprint, realistically next quarter | 1–3 weeks to find and onboard | Their queue, their priorities | Within days |
| Knows the target ERP | Learning on the deal | Depends on the person | Yes, deeply | Yes — sandboxes already live |
| Whose product it looks like | Yours | Yours | Theirs, more and more | Yours |
| Roadmap impact | A sprint or more | Management overhead | None, but you lose control | None |
| Cost model | Salary plus opportunity cost | Hourly, and it drifts | Billed to the customer, slowly | Fixed quote |
| Can become a product feature later | Yes | Rarely structured for it | No | Yes — built with that seam |

We are selective. You should be too.
Good fit
- B2B SaaS teams with an enterprise deal blocked on one specific integration
- Products that have to work with a customer’s heavily customized or on-prem environment
- Teams who need work started this month, not next quarter
- Situations where only a single customer wants the system
Not a fit
- Systems two or more customers want — build the reusable connector instead
- An AI or agent layer for that customer — see custom MCP servers
- Scripts and data migrations under a week of scope
- Providing extra staff or embedded full-time hires
Not selling software — running the systems yourself?
If you are not selling software — you are the business connecting your own ERP, CRM and tools to each other, or putting AI on top of them — that is the same engineering, sold differently.
- Connect the systems you already run — SAP, NetSuite, Dynamics 365, Salesforce and Coupa
- Implement the tools you buy: configuration, integration, data migration, testing and training
- Put AI on top — an MCP server over your own ERP, with confirmations and an audit trail
The point is speed without a permanent cost.
We start in days, not next quarter
One to three projects per engineer, on purpose. A deal blocker gets picked up while it still matters rather than joining a queue.
We have already met their ERP
Live SAP, Oracle, Coupa, Workday and Dynamics 365 environments on our side, and more besides. We have hit the custom fields, the unusual auth, and the rate limits before, on someone else’s project.
We separate it cleanly from day one
The customer-specific parts stay separate from the parts that would work for any customer, so moving this into your product later is a scoped job, not a rewrite.
One-off integration questions, answered.
An integration built for a single named customer’s environment that does not enter your product’s integrations library. It is scoped to their systems, their customizations, and their contract — and your other customers never see it.
Sometimes you should, and we will say so. The test we apply is whether a second customer is plausibly going to ask within a year. If yes, build the reusable connector and spread the cost across them. If no, a permanent feature means permanent maintenance for a single customer.
You. We work as an extension of your team — your repo or a repo you own, your branding, your release process. We can join customer calls under your name if that helps, or stay entirely behind the scenes.
Common, and usually fine. If it has an API, a file drop, a database, or even a queue, we can work with it. We are direct during scoping about where we have deep experience and where we would be learning on your time — and we price accordingly.
Yes, and we build with that seam in mind: the customer-specific parts stay isolated from the parts that generalize. If a second customer asks for the same system, the promotion is a scoped project rather than a rewrite.
Usually within days. We cap each engineer at one to three projects specifically so an urgent deal blocker does not sit in a queue. For the major ERPs we already hold sandboxes, so discovery does not wait for customer access.
By default you do, with our documentation and eight hours of post-launch support. Many teams add a small retainer for the first months, because a one-off integration for a strategic account tends to attract change requests early and then go quiet.
Fixed quote per integration after scoping, usually within 24–48 hours. Because the scope is a single customer and one environment, the quote is genuinely fixed — there is no hidden multi-tenant complexity waiting to be discovered.
