Integrations
Integrations that remove double work
Online store to accounting, vacancies to your ATS, orders to your carrier. Data enters the system once.
- Fixed price per phase
- One point of contact
- Design and development in-house

Why choose Peak Projects for integrations
Orders typed into the accounting system by hand, vacancies that need updating in three places, stock that never adds up. That is rarely down to the people. Usually an integration is missing.
We build integrations between the systems you already use. Through existing APIs where they exist, with custom work where needed. Examples include Dutch accounting software SnelStart connected to a B2B ordering platform, OTYS vacancies connected to recruitment sites, Mollie and PostNL connected to WooCommerce, and Bullhorn connected to a white-label platform.
Who it is for
- ✓Online stores that still enter orders into their accounting by hand
- ✓Recruitment agencies with vacancies in an ATS that also need to appear on their site
- ✓Wholesalers with an ERP that needs to connect to an ordering portal
- ✓Companies with a till, CRM or planning tool that does not talk to the website
No double entry
Data enters the system once and ends up everywhere it belongs.
Real time where it matters
Stock, prices and vacancies updated instantly. In batches where that is smarter and cheaper.
Built to be robust
Error handling, logging and alerts when something goes wrong. An integration that breaks silently is worse than no integration.

Process
How it works
- 1
Inventory
Which systems, which data, which direction. Often clear after one conversation.
- 2
Proposal
A fixed price per integration, with the assumptions written out.
- 3
Build and test
First in a test environment with real data. It only goes live once everything checks out.
- 4
Monitoring
After launch we keep an eye on the logs. If something goes wrong, you hear it from us, not from your customer.

FAQ
Questions about integrations

Question not listed?
You will get an answer within one working day.
Anything with an API or an export option. We have experience with SnelStart, Exact, Moneybird, OTYS, Bullhorn, Mollie, PostNL, Sendcloud, WooCommerce, Shopify, Gripp, HubSpot and various ERP systems.
Often it is, through exports, email processing or a connection at database level. We assess per case what is reliable enough.
A standard integration between two systems with a good API is usually built within a few days. Complex mappings or systems without an API take more. You get a fixed price in advance.
Then we update the integration. With a maintenance agreement that is included, otherwise we charge per change.
