Key takeaways
- Vergo codes AP invoices to projects, phases and GL accounts at the same time using AI inference from your own accounting structure, with no manual rule setup for each vendor type.
- Interior design firms need AP automation that codes invoices to projects, phases and item categories, and separates client purchases from firm expenses, not just GL accounts.
- Approval workflows should route by project, amount or GL account so designers can approve from their phone without holding up other projects.
- Regular ERP sync keeps project reports current for client billing, markups and budget tracking.
- Exception reports flag uncoded lines, stalled approvals and invoices that don't match the purchase order before they compound.

What makes AP automation different for interior design firms
Interior design firms working on a project basis need invoices coded to specific projects, phases and item categories, not just departments or GL accounts. A $12,000 fabric invoice might split across three residential projects, each with its own FF&E budget. Generic AP tools can't handle that allocation. Manual AP is too slow because designers and project managers are at client homes and showrooms, not at desks approving invoices, so approvals from a phone are essential. The system must also separate client purchases (billed through with a markup) from firm expenses, support purchase order checks against the approved specification, and give real-time project visibility for client billing. Without these capabilities, you're re-entering data manually or running blind on project profitability until month-end.
Step one: Audit invoice volume by vendor type
Start by categorizing your invoices by vendor type and frequency: fabric mills, custom millwork shops, lighting vendors, tile suppliers, workrooms and installers. Tag each invoice by dollar amount and recurrence. High-frequency, high-dollar vendors, like your primary fabric supplier, carry the most coding volume and belong at the top of your rollout. Low-frequency vendors, such as one-time custom artisans, matter less at first. This audit tells you where automation saves the most time and helps you sequence onboarding. Vergo proposes coding by inference from your own vendor history, so new vendors are coded on first sight without building rule libraries. Document the current cycle time from invoice receipt to ERP entry; this becomes your baseline for measuring improvement.
Step two: Map invoice coding to your project structure
Every invoice line must tie to a project, phase and GL account, for example Project 1041 > Procurement > Custom Upholstery. Build a standard item category list that mirrors how your ERP tracks project spend. If you use QuickBooks Online, that usually means customers/projects plus classes; in Sage Intacct, project and department dimensions; design-specific systems like Studio Designer track projects and item types. Interior design firms often add a phase layer (Design Development, Procurement, Installation) to track spending against milestones. Lock this structure before configuring automation; inconsistent categories will break reporting and client billing. Vergo infers the coding from your existing project structure and history, so there's no manual mapping per vendor. Share the list with project managers and designers so everyone uses the same language.
A practical example: coding a fabric invoice across three projects
A high-end fabric vendor sends a single invoice for $18,000 covering upholstery for three residential projects. Line one is $7,200 for Project 1041 (living room sofas), line two is $6,300 for Project 1055 (dining chairs), and line three is $4,500 for Project 1063 (bedroom headboards). Your AP system must split the invoice by line item, assign each to the correct project and FF&E category, mark it as a client purchase, and route each split to the responsible designer for approval. Once approved, each line syncs to your ERP as a separate project entry so monthly client billing, including markup, reflects actual procurement spend. Without this line-level allocation, you're either manually splitting invoices in Excel or billing clients from lagged, inaccurate reports.
Step three: Set approval workflows by project and threshold
Route invoices under $5,000 to the project designer; route above $5,000 to the controller or principal. Multi-project firms need parallel approval chains so one stalled invoice doesn't block others. If a designer is on-site for an installation, they should be able to approve by text with no portal login. With Vergo, employees submit receipts by text or from their phone, and approval workflows route by GL account, by amount or by project. For installer and workroom invoices, consider a two-stage workflow: the project manager confirms the work is complete, then accounting confirms payment terms and whether the cost is billable to the client. Build escalation rules so invoices stuck in approval for more than three business days notify the next approver. This keeps the pipeline moving and prevents month-end bottlenecks.
Step four: Sync approved invoices to your ERP and run exception reports weekly
Push coded, approved invoices into QuickBooks Online, Sage Intacct or your ERP automatically. Regular sync eliminates duplicate entry and keeps project reports current for client billing. Run weekly exception reports that flag invoices missing project coding, stuck in approval, or not matching their purchase orders. Controllers should review these every Monday before they compound. Common exceptions include vendors not yet in the system, invoices that arrived before the PO was logged, and split invoices where one project's approval is pending. Resolve exceptions promptly to maintain data integrity. Monthly reconciliation should confirm that every invoice in your AP system matches a corresponding entry in your ERP's project records.
How Vergo handles this
Vergo codes AP invoices, employee reimbursements and card spend through one AI-powered platform. Vergo proposes the coding by inference from your own accounting structure and project history, with no rule library to build, no keyword lists to maintain, and new vendors coded on first sight. Every coding shows why it was chosen, so a reviewer confirms in seconds instead of re-coding by hand. Transactions are ready to code the moment they arrive, and once processed, they sync into your ERP. Approval workflows are optional and fit how you already control spend: route by GL account, by amount or by project, or skip approval flows entirely and let policy flags catch only what breaks a rule. Employees submit receipts by text or from their phone with no portal login, and Vergo chases missing receipts itself. Approved invoices flow into your project records and general ledger in systems such as QuickBooks Online and Sage Intacct without re-entry.

Frequently Asked Questions
Can AP automation handle split invoices across multiple interior design projects?
Yes. Project-aware AP automation lets you allocate a single invoice across multiple projects by line item. A $15,000 furniture invoice can split 40% to Project A and 60% to Project B, each coded to the correct phase and item category automatically.
How does AP automation integrate with Sage for interior design firms?
Vergo does not integrate with Sage Intacct today; its API is open only to approved partner vendors. Each line carries the GL account plus dimensions such as project and department, eliminating manual journal entries. This keeps project reports accurate for monthly client billing and markups.
What if my designers are on-site and can't approve invoices at a desk?
Approvals from a phone solve this. Invoices route to designers with full project context: vendor name, project, PO reference and amount. Designers approve or reject in a reply. This removes the approval backlog common in design firms running installations and client visits.
How does AP automation affect month-end close for project-based firms?
AP automation speeds up month-end close by getting invoices coded and posted as they arrive. Controllers stop chasing missing invoices or correcting miscoded entries. Project reports, client billing and accruals are accurate before the close period begins.
Do I need to change my project coding structure to implement AP automation?
No. Quality AP automation platforms map to your existing structure. Your current project list, phases and GL accounts come across during setup. The system then uses them for suggestions and routing, so your team works with familiar categories from day one.
