Invoice & AR Automation — Closes the Loop, Not Just the Books
Where billing actually leaks
Connected pipeline, paid invoices
What we automate
Six common modules. Most clients install three or four in the first 28 days, then expand the pipeline from there.
-
Billable event capture
Time entries in Hubstaff, Harvest, or Toggl flow into invoice drafts. Project milestones in ClickUp, Asana, or Monday trigger milestone invoices. Recurring licenses generate on schedule. Nothing billable goes unrecorded.
-
Invoice generation
Drafts populate in QuickBooks, Xero, or NetSuite with line items, descriptions, customer info, and PO references filled from the source data. Finance reviews and approves — they don't re-type.
-
Recurring billing
Subscriptions, retainers, and recurring service fees generate on their cadence with proration logic for mid-cycle changes. Stripe, GoCardless, or invoice-on-net-terms — your model, your call.
-
AR aging dashboard
Live aging by client, days-sales-outstanding trend, chase-priority queue, and concentration alerts when a single client crosses a risk threshold. The cash conversation moves from 'let me run a report' to 'here's the screen.'
-
Automated follow-ups
Polite, well-paced reminder sequences that escalate at 7/14/30/60 days. Copy written in your voice, not collections-agency boilerplate. Bounces and out-of-office detection rerouting to the right contact.
-
Dispute & write-off flow
When a client disputes a line item, a structured flow captures the reason, routes to the account owner, generates the credit memo if approved, and updates AR — all logged for audit. Write-offs stop being a quarterly cleanup project.
Real outcomes — Contrail Financial case
What changed when invoice & AR automation went live
How the pipeline runs
Four stages. Every transition is automated; finance owns the exceptions.
- 1
Stage 1. Billable event
Time entry submitted, project milestone hit, or recurring schedule triggers. The event lands in the queue with all metadata — client, project, billable rate, contract terms — already attached.
- 2
Stage 2. Invoice draft
Draft auto-generates in QuickBooks, Xero, or NetSuite with the line items, descriptions, customer details, PO references, and contract terms populated. Tax logic, currency conversion, and discount rules applied per the contract.
- 3
Stage 3. Review & approve
Finance sees the draft in a review queue with anomaly flags (outside-typical-range amount, missing PO, expired contract). Routine drafts auto-approve after a configurable timer; flagged drafts wait for a human.
- 4
Stage 4. Send & follow-up
Invoice ships from the accounting tool. AR aging dashboard updates. Follow-up sequence starts on the schedule the contract terms require, with human-voice copy. Payment events close the loop and update revenue recognition automatically.
Where AR automation breaks (and what we do instead)
-
OFF-THE-SHELF AR TOOLS
Bill.com, Chaser, Upflow, and Tesorio win for high-volume B2C or simple SaaS billing where every invoice looks the same. They scale follow-up across thousands of customers efficiently. We integrate with them when they fit. -
WHERE THEY FAIL
Service businesses with custom billing — T&M plus fixed-fee plus milestone plus retainer, all on the same client, with different terms per contract — break the off-the-shelf templates. Approval routing, dispute flows, and credit memos need real logic, not a wizard. -
WHERE WE WIN
When billing has real business logic — multi-product, multi-rate, multi-term, multi-currency — we build the pipeline that codifies that logic explicitly. The off-the-shelf tool stays for the customer-facing follow-up; we handle the messy middle.
The Backbone
The Invoice & AR Backbone
One deep module that runs the pipeline, plus two lighter modules for specialized models.
Invoice & AR Module
The complete pipeline from billable event to paid invoice:
Billable Capture
Time, project milestones, and recurring schedules all become invoice candidates automatically. Nothing billable gets missed; nothing non-billable becomes an invoice.
Invoice Generation
Drafts populate in QuickBooks, Xero, or NetSuite with line items, terms, tax, currency, and PO references already filled. Finance reviews; nobody re-types.
AR Aging Dashboard
Live view of open balances by client, DSO trend, chase-priority queue, and concentration alerts. The same data your bank wants to see when you ask for a credit line.
Follow-up Sequences
Polite, well-paced reminder cadences in your brand voice. Escalation rules, bounce detection, and pause-on-dispute. Doesn't sound like a robot because it isn't.
Dispute Flow
Structured capture, routing, credit memo generation, and audit trail. Write-offs stop being a quarterly cleanup; they're a handled exception.
Margin Reporting
Live per-client and per-project gross margin pulled from time tracking, accounting, and project data. Surfaces unprofitable clients before the year-end review. Connect to our /systems/operations-dashboard-reporting module for the full reporting stack.
Subscription Billing
For SaaS, retainers, and recurring services — proration logic, plan changes mid-cycle, dunning, and Stripe or GoCardless integration. We model the billing logic explicitly rather than trying to bend an off-the-shelf subscription tool to fit.
Stack
Tools we connect to
We've worked with 137 different tools in production environments. If yours has an API, we can connect it.
Why 2V
What makes our Invoice & AR Backbone different
Native QuickBooks / Xero / NetSuite
We work inside your accounting tool's native API. Invoices, customers, and payments live where your bookkeeper expects them — not in a shadow system that requires reconciliation.
Audit trail by default
Every state change, approval, dispute, and credit memo is logged with timestamps and actors. When an auditor or a customer asks, the answer is one query away.
Human-voice follow-ups
AR follow-up copy that sounds like a real person — because we write it with your finance lead, not generate it from a template. Clients pay faster when they don't feel like they're talking to a collections bot.
Margin-aware
Invoicing without margin visibility is half a job. The pipeline surfaces per-client and per-project margin so unprofitable accounts get visible before renewal — not at year-end.
Bookkeeper-friendly
We don't replace your bookkeeper. We make them dramatically faster by giving them clean drafts to review instead of raw data to enter. Most bookkeepers we work with end up advocating for the system.
Engagement & pricing
We start with a paid workshop, then install the Foundation pipeline in 28 days, then keep it running on a monthly retainer. Each phase delivers measurable value before you commit to the next.
If we can't show ROI inside six months, we don't take the project.
- Discovery workshop: $2K — Map the current billing flow, score the leaks, prioritize the 28-day build.
- Foundation Invoice & AR build: $7K–$13K — Install the pipeline (typically billable capture + invoice generation + AR aging + follow-up).
- Ongoing Expansion retainer: From $1K/month for monitoring + small fixes; $3.5K/month for active expansion; $6.5K/month for embedded finance-ops engineering.
Frequently Asked Questions
If you have a question, chances are you'll find the answer below.
Do we keep QuickBooks / Xero or do we need NetSuite?
Keep what you have. QuickBooks Online works for most service businesses up to ~$10M. Xero is the natural choice if you're already on it. NetSuite earns its keep only when you have multi-entity consolidation, advanced revenue recognition, or genuine ERP needs. We tell you on the workshop if you're outgrowing your current accounting tool — most clients aren't.
Can it handle T&M, fixed-fee, and subscription billing?
Yes — and most of our clients have all three running at once for different accounts. We model the billing logic per contract type and route the right events to the right pipeline. Off-the-shelf tools choke on this; explicit logic handles it cleanly. See our finance automation pillar for the broader department view.
How aggressive is the AR follow-up — does it sound like a robot?
It doesn't, because we write the copy with your finance lead during the workshop. Cadence is configurable per client tier (a $200K/year client gets a different sequence than a $5K one-off). Bounces and out-of-office reroute to the right contact. Reply detection pauses the sequence so a human conversation doesn't get interrupted by an auto-nudge.
What about international payments and multi-currency?
Multi-currency is supported natively — Stripe, Wise, and most accounting tools handle the conversion. We model the FX logic explicitly (which currency invoices, which currency books, which rate to use, when to recognize FX gain/loss) and surface it on the dashboards. International AR follow-up respects local norms (Net 30 isn't universal).
Can it integrate with our time-tracking?
Yes. Hubstaff, Harvest, Toggl, and Clockify all have APIs we use natively. Time entries flow into invoice drafts with the project, rate, and billable flag preserved. If your team uses a custom system, we integrate with it directly. See our automate invoices post for a worked example.
Will it conflict with our bookkeeper?
No — and your bookkeeper usually becomes a fan within 30 days. We give them clean drafts to review instead of raw data to enter. They keep ownership of the chart of accounts, journal entries, and month-close. The Backbone handles the volume work; the bookkeeper handles the judgment work.
How does it handle disputes and credit memos?
Structured flow. Client raises a dispute (via email parsed by the system, a portal form, or AR follow-up reply detection). The dispute routes to the account owner with full context, approval routes if a credit is warranted, the credit memo generates in the accounting tool, and AR updates. Every step logged for audit. Disputes stop sitting in someone's inbox.
What's the difference vs Bill.com / Stripe Billing?
Bill.com is great for AP, decent for AR; Stripe Billing is great for SaaS-style recurring. Both are off-the-shelf and shine when your billing fits their model. We win when billing has real business logic — mixed billing models, complex approval, custom dispute flow, multi-source billable capture. We also integrate with both if they fit a slice of your needs. See our PO automation post for the AP-side analog.
