Mission Order for NGOs: Managing Field Travel End to End

A field mission is not a document: it is a chain. Justified request, approval, booking, signed mission order, per diem calculation, possible advance — then on return, boarding passes, receipts, mission report and payment. Every missing link becomes a potential ineligible expense — the subject of our ineligible expenses guide.

What a mission order must contain

The official document authorising travel must carry: the traveller's identity, the mission's purpose, dates and destinations, the project and budget line to charge, the applicable per diem regime, and the signature of the authorised person (with an up-to-date delegation of authority). Donors add their own requirements: insurance, a pre-departure security memo, and the reference per diem policy.

The 3 classic friction points

1. The disputed per diem: who booked the accommodation? Was it free? The applied rate (full or reduced) must follow a written rule, not a negotiation on return.
2. The unsettled advance: a mission of more than a few days justifies a field advance — which must be cleared by the mission expense report, never forgotten.
3. The incomplete TERF: without boarding passes and a mission report, the whole expense can fall in audit.

The Abvius workflow: from request to payment, no retyping

The Abvius Travel module chains the entire mission in one flow:

• A 3-step request: project and analytic code, journeys (return or multi-destination, all transport modes), mission details — with the accommodation choice automatically determining the per diem regime, a mandatory passport check, visa needs, and an advance request opening beyond 5 days.
• Approval then logistics: the project manager approves, the logistics team books, enters the daily per diem (with a link to the European Commission's reference rates) and uploads tickets — the traveller is notified "Tickets Available".
• A one-click mission order as PDF, with logo, registration number and the project director's signature, alongside the pre-departure memo and the annual insurance certificate.
• A guided TERF on return: boarding passes, per diem recalculated by rule (organisation-booked accommodation = reduced rate; otherwise 100%), ancillary expenses with receipts and currency conversion evidence, a mandatory mission report.
• Automatic payment and charging: finance pays, the analytic code's budget updates including exchange fees, and the complete file (mission order, tickets, TERF, evidence) is archived, audit-ready — Abvius's audit-ready file principle, hosted in France on HDS servers.

It all connects to timesheets and the HR workspace — see our humanitarian HRIS guide — and works for your partners, included at no extra cost.

In practice

Write your per diem rule down, wire it into the tool, and require the TERF before any reimbursement: three decisions that remove 90% of mission disputes. Next step: our humanitarian procurement guide for the logistics side of your projects.
