build
connect the systems your business already runs on.
we build reliable integrations between websites, apps, erp, accounting, payments, logistics, and the rest of your stack, so data moves once, correctly, and without manual re-entry.
growth usually means more tools, and more places where the same customer, order, or invoice gets typed twice. fossasoft builds the connections that keep systems aligned.
that includes rest apis, webhooks, middleware, and careful mapping of fields and edge cases so a failed sync is visible and recoverable.
integrations are engineering work with operations consequences: we design for retries, logging, and ownership, not just a happy-path demo.
what we do
system-to-system connections
link ecommerce, crm, accounting, erp, shipping, booking, and custom apps so records stay consistent.
apis and webhooks
consume and expose apis, handle events, and design contracts that other systems can rely on.
data mapping and transformation
translate fields, statuses, tax rules, and catalogs between platforms that were never meant to talk.
error handling and observability
retries, dead-letter paths, logs, and alerts when a sync fails, silence is not success.
middleware and sync services
lightweight services that sit between tools when direct point-to-point links become fragile.
how we work
- we inventory systems, owners, and “source of truth” for each data type before writing code.
- edge cases, refunds, duplicates, partial updates, are designed in, not discovered in production.
- we test with real payloads and failure modes, not only sample json.
- documentation names what syncs, how often, and who to call when it breaks.
typical projects
- store to accounting or erp order sync
- crm enrichment from website and support tools
- payment and payout reconciliations
- shipping and inventory bridges
- custom api layers for partners or mobile apps
what we deliver
- working integrations or middleware
- field mapping and sync rules documented
- logging and failure alerts
- credentials and environment notes
- optional monitoring retainer
what you get
systems that share data without constant copy-paste or mystery mismatches.
your team trusts the numbers in each tool because the connections were built to be maintained.
