Turn scattered invoices into a proof packet people can trust.
ProofPack is a concierge proof-of-income and deliverable-proof workflow for freelancers: upload invoices, time sheets, bank exports, contracts, and delivery links; get back the clean packet a lender, broker, accountant, or disputed client can review.
Validation page only. Early users get one manual packet from redacted files before bank or accounting integrations are built.
proof packet
14 invoices · 11 deposits · 3 gaps
Unmatched deposit
Stripe payout has no invoice number or client alias
Missing proof
March consulting invoice paid, but contract/SOW link is absent
Clean trail
Acme Q2 invoices match bank deposits and delivery notes
Packet note
“Income is irregular but traceable: invoices A-101 through A-114 map to 11 verified deposits; three files need attachment before lender review.”
Narrow customer
Freelance developers, designers, and consultants with irregular client income who need proof for a mortgage, loan, apartment, visa, accountant, or client dispute.
Paid problem
Rejected applications, delayed underwriting, unpaid disputed milestones, and hours of manual reconciliation from invoices, bank exports, time sheets, and delivery links.
Landing test
Join to test a concierge proof packet before ProofPack asks for accounting, bank, payment-processor, or project-tool integrations.
Day-in-the-life pain
The lender asks for proof. Your income story is scattered across five tools.
A freelancer can have healthy income and still look messy on paper: one client pays by ACH, another through Stripe, invoices live in a template, hours are tracked in a sheet, and project proof is split across GitHub, Figma, email, or Drive. The painful job is not creating another invoice; it is explaining the trail to someone outside the business.
Input
Upload invoice PDFs, time sheets or CSVs, bank/payment exports, client contracts or statements of work, and optional delivery links from GitHub, Drive, Notion, Figma, or email.
Checks
ProofPack matches billed periods to paid deposits, flags missing invoices or unmatched payments, groups irregular income by client and month, and notes delivery proof gaps.
Output
A lender/client-ready packet: income summary, invoice-to-payment trace, missing-proof checklist, dispute timeline, and exportable PDF/CSV appendix.
Why the workaround breaks
Spreadsheets help you run the business. They do not automatically persuade a reviewer.
Public threads show freelancers and small shops already leaning on sheets for hours, notes, invoices, and client reports. That works internally until a lender, broker, accountant, or disputed client needs a coherent external packet with a clear chain of evidence.
Invoice-to-payment trace
Match invoice numbers, billed dates, paid dates, payment processor lines, and bank deposits so irregular income is easier to explain.
Proof gap checklist
Show missing invoices, unlinked payments, unclear client names, absent contract snippets, or deliverables without timestamped support.
Lender-safe summary
Package the story a mortgage broker, loan officer, or underwriter needs without exposing unnecessary client details.
Dispute-ready appendix
Keep optional milestone and delivery evidence for client disputes: scope notes, approval links, shipped files, and timestamps.
Concierge-first validation
Early users receive one manual proof packet from redacted exports before any bank, accounting, or project-tool integrations are promised.
Evidence, not proof
The repeated signal: small operators can invoice, but proof still gets assembled by hand.
The evidence does not prove demand. It justifies a focused validation question: will freelancers join a waitlist or share redacted files for a manual proof packet before another generic finance app is built?
HN Ask · contractors still turn hour sheets into invoices manually
A one-person contractor describes keeping date, hours, and notes in Google Sheets, then copying totals into another invoice-looking sheet and printing to PDF each billing cycle.
HN Spreadsheet thread · one-man shops want timesheets and invoices without macros
A small-business commenter says their monthly workflow depends on a lightweight spreadsheet for accounting, timesheets, and invoices, but they do not want to grow custom macros around it.
HN Automation thread · recurring client reports are assembled in Excel
A team reports that engineers used to spend hours every week manually preparing stat reports in Excel to send to enterprise clients until they templated the process.
GitHub issue · freelancers need coherent proof-of-income packets
A public problem statement describes freelancers applying for mortgages or major loans needing a coherent proof-of-income package from irregular client payments and invoices.
GitHub issue · disputed deliverables need organized proof
Another public problem statement describes freelancers needing timestamped proof of deliverable completion when a client disputes scope or milestone completion.
Objections
Why this deserves its own landing test.
Why not QuickBooks or Xero?
Accounting tools store transactions, but freelancers still need an explanatory packet that connects irregular invoices, payments, contracts, and proof for a specific external review.
Why not a spreadsheet template?
Templates still leave the freelancer reconciling deposits, client aliases, missing invoices, and delivery proof by hand. ProofPack turns exceptions into a review list.
Will this replace an accountant?
No. It prepares organized evidence for a lender, broker, client, or accountant. The first product is a packet builder, not tax advice.
What about privacy?
Validation starts with redacted files and a manual packet. The landing test measures whether the pain is strong enough before deep integrations or document storage are built.
What early waitlist users get
One manual packet from redacted files: income summary, invoice-to-payment trace, missing-proof checklist, and a PDF/CSV appendix you can hand to a lender, broker, accountant, or client.
Validation target: 5+ qualified freelancer emails or 2+ users willing to share redacted invoices, payment exports, and proof links for a concierge packet review.
