Certificates and deadlines
Contracts run on certificates, and certificates run out. The dates are already set.
For a firm whose deadlines come from a regulator, a contract or a statute: they do not arrive together. Each one sits with a different body, on a different clock, in a different format, and none of them is anybody's whole job.
Four duties with dates attached
Every duty below was set by somebody else, and every consequence of missing one lands on you.
Anti-money-laundering paperwork: for a law firm that signs the yearly declaration
Keeping certificates current: for a supplier whose contracts depend on them
The statements bigger firms publish: for a firm that has just crossed the line
Norwegian filing deadlines: for a firm with a company in Norway
Who this is for, and who it is not
For a firm whose deadlines come from a regulator, a contract or a statute rather than from a competition.
If what you're looking at is a tender, grant or award instead, that is Before you commit and The writing.
Where to start
The first read is free, and it looks at the dates that gate contracts you already hold. Ask what is out there for a firm like yours, or name what you are going for. Ongoing help with certificates and deadlines is a different service, and if that's what you want, the form has a space for you to say so in your own words.
