A freelancer month: invoices, late payment, travel, and foreign software

A source-to-handoff bookkeeping workflow for freelancers and consultants.

Summary

Freelancers and consultants usually have fewer transaction types than retailers, but timing and evidence matter: proposals become contracts, work may span months, invoices can be paid late, travel and subcontractor costs need purpose, and foreign clients or software suppliers can create VAT questions. A workable system connects each engagement to its contract, delivery evidence, invoice, payment and related costs. The choice between EÜR and balance-sheet accounting changes some timing and closing questions, so do not build the workflow solely around when money reaches the bank.

Key takeaways

  • Link contract, performance, invoice and payment for every material engagement.
  • Separate billable work, issued invoices and collected cash.
  • Capture business purpose for travel, tools and subcontractors promptly.
  • Review foreign clients, reverse charge and recurring software suppliers early.

Confidential client work should not be copied into bookkeeping unnecessarily. Retain enough evidence to support the commercial event while following contractual and data-protection duties.

Monthly routine

  1. Review active engagements and completed billable milestones.
  2. Issue invoices consistently and track credit notes.
  3. Reconcile receivables to bank collections.
  4. Collect subcontractor, software, travel and home-office evidence as applicable.
  5. Identify work or costs spanning periods for professional review.
  6. Check foreign supplier and customer cases before VAT reporting.
  7. Compare business pipeline, invoices and cash without treating them as the same metric.

Worked month: seven sources, different next steps

A synthetic consultant month contains two client invoices for €6,000 and €3,500; the older €6,000 invoice is paid late this month; a US software invoice for $240; three travel receipts, one missing the participants and business purpose; a €1,800 subcontractor invoice; and a €320 business purchase paid from the owner's private card.

DeinHans can organise the sources, connect payments, keep receivables visible, ask for missing business facts and prepare exceptions for the accountant. It does not manage projects or time sheets, decide cross-border VAT, or determine whether a mixed or private payment is deductible.

Common difficulties

  • Work is completed but invoicing is delayed.
  • One payment settles several invoices or includes expenses.
  • A foreign customer requests wording the consultant does not understand.
  • Recurring software invoices change supplier entity or VAT treatment.
  • Travel receipts lack participants or business purpose.
  • Personal and business card activity are mixed.

Professional boundary: EÜR, balance-sheet accounting, VAT, business expenses and cross-border services have specific rules and elections. Confirm the freelancer’s method and transactions with a qualified adviser.

What DeinHans can support

DeinHans can connect invoices, expenses, payments, questions and period status, helping the freelancer and accountant work from the same evidence. It does not replace contract management, professional tax decisions or the owner’s explanation of business purpose.

Quarterly owner review

Compare contracted work, delivered but unbilled work, issued invoices, overdue receivables, collected cash, recurring commitments and upcoming tax payments. These views answer different questions. Keeping them separate helps the owner plan liquidity without confusing a healthy bank balance with completed bookkeeping or taxable profit.

Project and subcontractor controls

For fixed-price work, retain milestones, change requests and acceptance. For time-based work, preserve approved time or deliverable evidence without copying unnecessary client-confidential content. Reconcile subcontractor services with the period and project they support, and confirm that an invoice belongs to the correct legal entity.

Do not net a subcontractor payment against customer revenue merely because both relate to the same project. Gross activity and costs remain visible; any agent or pass-through arrangement needs contract-based professional review.

Owner-paid and mixed expenses

If the freelancer pays a business item privately, keep invoice, proof of payment, purpose and reimbursement or owner-account treatment together. For mixed-use software, telephone, travel or home costs, capture the factual use and let the adviser determine the permitted treatment. A card name alone cannot establish business purpose.

Capacity and continuity

Schedule a weekly evidence routine and a monthly reconciliation slot. Define a substitute or documented handoff for absence, even in a one-person business. Keep source exports and credentials in a controlled business location, not only on a personal device. A simple process is resilient when another authorized person can understand outstanding invoices, deadlines and unresolved questions.
