Claims are not lost.Delays are not a surprise.Certificates get paid on time.
Tessera ties the contract, the programme, the site record and the money together, so claims are not lost, delays are not a surprise and certificates get paid on time. Every number can be traced to its source.
What it protects
The first three worries of every contracts manager.
"We missed a notice time-bar and lost a claim."
Every event has a notice clock
Nothing lapses unseen. The dashboard watches entitlement and time-bars, and alerts flag closed windows and overdue claims.
Contracts → Notices & Time-Bar
"We don't know how late we really are."
Planned against actual, with a forecast
Physical progress against time elapsed, a forecast finish date and the reason, from the same record the programme uses.
Management Dashboard → Programme
"EOT claims are written months late, and weak."
The delay record builds the claim
A delay can name the activity it held up and the safety incident behind it, so the claim is assembled as events happen.
Contracts → Claims & EOT
…and the next three.
"Variations are agreed verbally and never priced."
Instruction, variation and cost in one chain
Instructions become variations with their cost impact; omissions show negative; approval follows a path you can see.
Contracts → Instructions → Variations
"The client pays late and we don't see the cash gap coming."
Certificates, retention and cash, month by month
Certificate readiness, days late and an estimated late-payment interest for each certificate, retention held, and a cash-flow forecast.
QS → IPC Readiness · Finance → Cash-Flow
"The monthly report takes a week and nobody trusts it."
One click, from the live data
The monthly report is produced from the same record everyone else is already working in, so the numbers agree.

Where Tessera is today
In pilot use, and set up one company at a time.
Tessera is the tool behind the contract-controls service offered by its designer, Bernard Nasinyama. We load your programme and bill of quantities, set up your people and run the first controls with you, typically within about two weeks, then your team carries on using it. We would rather serve one company properly than many badly.
