Nexus Build · QuickBooks-first construction AP

Keep QuickBooks. Control the work around it.

Nexus adds the job-cost, lien-waiver, retainage, compliance, and approval workflows construction finance teams need—without asking them to replace their ledger.

Illustrative product workspace

Operational proof

One controlled path from invoice to job cost.

Import vendors, bills, and purchase orders from QuickBooks

Code costs by job, phase, cost code, and cost type

Hold payment for explicit waiver and insurance requirements

Post invoice-linked actual cost and retainage on approval

01

Bring in the accounting context

Start with QuickBooks vendors, bills, and purchase orders so teams work from familiar records rather than rebuilding a parallel ledger.

02

Review construction coding

Operators confirm the job, project phase, cost code, and cost type at line level before approval.

03

Enforce project requirements

Nexus creates missing waiver obligations, checks job-specific insurance, and records any approved override with its reason.

04

Post and reconcile

Approval posts actual job cost and retainage to source-linked ledgers; approved bills can then move back to QuickBooks.

The operating model

Construction depth without an ERP migration.

QuickBooks remains the accounting source of truth. Nexus becomes the calm control layer for the project-specific work that spreadsheets and generic AP tools leave behind.

Qualified walkthrough

Bring one real workflow.

Tell us how you use QuickBooks, how many projects and invoices you manage, and where waivers or retainage break down. We’ll shape the session around that operating reality.
