A SaaS company's enterprise customers needed integrations the product didn't have. We built an integration middleware layer in 10 weeks.
The client's B2B SaaS had 40 enterprise customers, all of them asking for integrations with different tools (Salesforce, HubSpot, Slack, Microsoft Teams). The engineering team was too small to build and maintain 12 integrations. We built a webhook-based integration middleware that let the client ship integrations 5x faster.
Enterprise customers demanding CRM and communication integrations that would each take 4–6 weeks of engineering time to build
The client ran a project management SaaS for professional services firms. 40 enterprise accounts, $2.4M ARR. Every enterprise renewal conversation in the past two quarters had included a request for a specific integration: Salesforce for the sales team's account records, HubSpot for companies using HubSpot CRM, Slack for project notifications, and Microsoft Teams for customers in corporate environments.
The engineering team was 3 people. Building and maintaining each integration in the core product would take 4–6 weeks each — and once built, each integration would require ongoing maintenance as the integrated APIs changed. At 4 integrations × 5 weeks average: 20 weeks of engineering time. With a 3-person team, that meant 7 months of integration work that produced no new features.
The alternative: an integration middleware layer that abstracted the integration complexity, maintained the integrations in isolation from the core product, and created a pattern for shipping new integrations faster.
Integration middleware with pre-built Salesforce, HubSpot, Slack, and Teams integrations — enabling new integrations in 2 weeks instead of 6
Trigger-action model: events in the SaaS trigger configured actions in connected
Each integration defined as: Trigger (e.g., "project status changed to Complete"
Customer-configurable via an integration setup UI within the SaaS product **Sale
One honest number to start.
Fixed-scope, fixed-price. The number below is the starting point — final scope is built from your brief.

Three steps, every time.
The same repeatable engagement on every project. No surprises, no mystery, no billable ambiguity.
Brief & discovery.
We send you questions, then get on a call. Output: a written scope with every step, feature, and integration listed.
Build & ship.
Fixed schedule, weekly reviews. No scope creep unless you change the scope — and if you do, we reprice it transparently.
Warranty & retainer.
30-day warranty on every launch. Most clients stay on a monthly retainer for ongoing features and maintenance.
Results
- 4 integrations shipped in 10 weeks (vs. 20 weeks estimated for core product approach)
- 3 enterprise renewals closed within 30 days of integration launch, citing integrations as the deciding factor
- New integrations now take 2 weeks to build and deploy using the middleware pattern

Questions, answered.
Each integration is an isolated module. When a connected API changes, only that module requires update — the SaaS core product is unaffected. The middleware deploys independently from the SaaS product.
The integration middleware exposes a webhook endpoint that customers can send events to, and a REST API for triggering actions in the SaaS from external systems. Customers with technical resources can build custom automations on these primitives.
Integration middleware with 4 pre-built integrations: from $35k. Fixed-price.
