If you are undertaking work and doing so on a self employed basis, not having terms can create undue problems and hassles.
Terms do not have to be complicated or shrouded in legal jargon. They simply need to document the work you are undertaking and how you expect to be paid.
Payment terms, can be as simple as detailing when you want paying and how? Cash, cheque or if Bank transfer, sort code and account numbers should be added.
Terms can be expanded to include cancellation charges. Be reasonable but be clear.
Minimum requirement to do the work can be included. If you need materials or supporting staff, you need to make it clear what you will expect as a minimum for you to be able to deliver your work, and the outcomes if these are not met.
Terms can be developed and added to, they are flexible and being your document, you can amend to suit different jobs and clients.
Terms should be signed and dated by the client before the work is done. This way there can be little disagreement as to their acceptance. This isn’t always possible, so in certain circumstance it can be suitable, simply adding them to the invoice. This means that the client knows your expectations and if there are any problems or issues, these can be sorted sooner rather later, with amendments made for future work or even both parties choosing to part ways with only one invoice be contentious and not several.
