How to connect Houzz Pro to Foundation Software

Houzz Pro and Foundation Software sit on opposite sides of the construction software market. Houzz Pro is built for residential builders and remodelers — design boards, client portals, lightweight estimates, and a QuickBooks-first accounting bridge. Foundation Software is built for commercial and heavy-civil contractors — job cost accounting, certified payroll, AIA billing, equipment tracking. They serve overlapping but different buyers, and neither has a strong commercial incentive to build a direct connector to the other.

The result: if you're a builder who runs project management in Houzz Pro but books cost in Foundation (a common setup for growing residential GCs taking on light commercial work), every job moves through a manual seam. The seam is where verification typically fails — line items get re-typed, change orders get assumed, and cumulative billing drifts from what was actually approved on the project management side.

1. CSV export from Houzz Pro, manual entry into Foundation. The most common pattern. The Houzz Pro project lead or office manager exports the approved estimate as CSV, then a Foundation user re-keys it as a job budget with cost codes. Every change order approved in Houzz Pro gets manually added as a budget revision in Foundation. Invoices from subs come in via email, get logged against the Houzz Pro project, then re-entered as AP in Foundation. The handoff lag is typically 1–3 days, and the cumulative re-keying error rate is meaningful — usually 1–3% of project value over the life of a job.

2. AIA G702/G703 progress billing as the bridge. On projects with formal progress billing, the AIA G702 application for payment and its G703 continuation sheet become the canonical document. Houzz Pro produces the schedule of values, Foundation books the cost. The G703 is the line-item ledger both sides reconcile to. Cleaner than CSV but only works if every change order has been folded into the G703 — and that's where verification fails most often.

3. Middleware (Zapier, Make, custom scripts). Some builders set up Zapier or Make to push Houzz Pro estimate approvals and CO approvals into Foundation as draft journal entries. This reduces re-keying but doesn't solve the verification problem — it just automates the handoff. If the Houzz Pro side has wrong line items or a missing CO, the middleware faithfully copies the error into Foundation.

Stale quote versions. Houzz Pro shows the most recent estimate. Foundation shows the budget that was booked when the job started. If estimates were revised after the initial budget was set, the two systems drift — and invoices get approved against whichever side the reviewer happens to check.

Change orders without budget revisions. A CO gets approved and signed in Houzz Pro. The PM moves on. Foundation never gets the budget revision. Months later, the job appears over budget in Foundation — but it isn't, the budget just never got updated. Or worse: the CO was billed by the sub, but Foundation has no record of it, so it sits in suspense or gets booked to the wrong cost code.

Cumulative overbilling across vendors. Houzz Pro shows invoices per project. Foundation shows AP per vendor. Neither natively shows cumulative billing per vendor per project against the committed subcontract. A sub can be inside budget on each individual invoice while being substantially over commitment in total — and the gap between the two systems is precisely where this goes undetected.

Retainage and lien waivers. Houzz Pro is light on retainage tracking. Foundation handles it well. If retainage is withheld in Foundation but the Houzz Pro invoice approval workflow ignores it, the PM may "approve" 100% of an invoice that Foundation will only pay 90% on — creating a payment discrepancy with the sub that erodes trust.

The pragmatic answer for most builders isn't "pick one system." Houzz Pro is good at what it does, Foundation is excellent at what it does, and forcing your office to abandon either is rarely worth it. The answer is a verification layer that sits in front of both systems and checks every quote, change order, and invoice against the approved scope — regardless of which system holds the record.

This is what Kiron is built for. Forward your project email inbox to Ella. She reads every incoming quote, CO, and invoice, matches it against approved scope and signed COs, computes cumulative spend per vendor, and produces a verified decision packet — before anything gets entered into Houzz Pro or Foundation. The systems of record stay the same. The verification just stops being a re-keying exercise.
