We had some work done in 2014. We have two paper invoices, one for a deposit of £1k and one for final payment of £3k less £1k deposit = £2k (all figures approximate to give scale).
We got an email today saying the company's accountants have flagged up that the deposit wasn't paid. The company are a bit confused - they wouldn't normally proceed without a deposit - but they can't find evidence of payment and have asked us to look and let them know how and when we paid. We can find evidence of other payments (before and since) but not this £1k.
It is conceivable that we paid out of a now-closed account, but most likely we didn't pay that deposit.
Where do we stand? They are a good local company with whose work we have been happy, and who we will probably use again in the future. But we can't afford to pay them £1k at this precise moment. Probably in about three months we could.
How do you think I should reply to their email? Am I generously offering to pay them in the nearish future, or am I begging them to let us off the hook for another few months?
