Procurement intelligence for the teams who sign the contracts
Stipula normalizes competing vendor quotes, catches the buyer-hostile clauses buried in your MSAs (take-or-pay minimums, standby at full day rate, uncapped fuel surcharges), and hunts down the duplicate spend hiding in your ledger. You get the number, the flag, and the exact lever to negotiate. Sign smarter, pay less.
A negotiation aid, not legal advice.
The fine print is winning
These aren't edge cases. They're the standard terms in most oilfield service agreements, and they're negotiable if you catch them before you sign.
Compare vendors
Three vendors, three billing schedules, three sets of features, and no honest way to compare them on the back of a napkin. Enter the quotes, or upload them as you received them: PDF proposals, pricing spreadsheets, a pasted email. Stipula extracts the numbers and normalizes everything to one annual figure.
You get a weighted score (cost against the features you actually require), the warnings that matter (long lock-ins, fat setup fees, a missing must-have), and a per-vendor set of negotiation levers. Not "this one's cheaper." This one's cheaper, here's the $9,120 gap, and here's what to ask for.
Contract review
Paste the contract or upload it as you got it. Stipula reads the whole document and flags what works against you, with the offending line, why it matters, and a concrete way to negotiate it. Auto-renewal traps, uncapped escalation, one-sided indemnity, low liability caps, data-ownership grabs, and the oilfield terms most tools miss: take-or-pay, standby, mob/demob, fuel surcharge.
Then it checks for what isn't there: the price cap, the termination right, the audit rights, the breach notice. When you're ready, it drafts the negotiation email for you, ready to send.
A negotiation aid, not legal advice.
Spend audit
Export your transactions (CSV, XLSX, or a PDF statement), and Stipula reconciles them the way a sharp AP clerk would, only faster. Same vendor and amount two days apart? Double-billing. "Halliburton Co." and "Halliburton Energy Services"? One vendor, two accounts. A monthly line that keeps creeping up? Price-creep, flagged before it becomes the new normal.
It maps overlapping service categories, catches recurring subscriptions you forgot you had, and totals what's recoverable, so the next spend review starts with answers, not spreadsheets.
Where it earns its keep
H2S / GAS MONITORING
WellGuard, PetroSense and RigWatch: monthly, discounted, and annual billing normalized to one number. PetroSense's missing SCADA integration and 36-month lock surfaced before the PO. Recommendation and a $9,120/yr gap, on one page.
Nº 01
WATER HAULING
Apex Water Hauling's renewal checked against Basin Water Logistics, and an $8,450 haul billed twice, two days apart, caught in the same pass. The minimum got reset to a good-faith target.
Nº 02
WIRELINE MSA
Halliburton and ProWire quotes on one ledger; a 90-day auto-renewal and an uncapped fuel surcharge flagged with time left on the clock, and the negotiation email drafted from the findings.
Nº 03
PRODUCTION CHEMICALS
ChemTreat's monthly line drifted from $12,000 to $13,800 across the quarter. Not a new PO, not a mistake: a +15% price-creep, flagged the moment it broke pattern.
Nº 04
SCADA SOFTWARE
FieldComm's steady $4,500/mo confirmed as a recurring subscription, and its telemetry overlap with the H2S vendor surfaced as a consolidation candidate, not a line item.
Nº 05
RIG PARTS · NOV
An NOV parts invoice read against the field ticket, with the missing audit-rights clause flagged, so when the numbers don't match, the overbilling is actually recoverable.
Nº 06
How it works
Paste the text, or drop the file as you received it: PDF, DOCX, XLSX, a pasted email. Quotes, contracts, statements. No reformatting.
OpenAI's GPT-5 does the deep read, and it always fails soft to a deterministic rule engine. No key, no outage, no problem: you still get the analysis.
A ranked ledger, flagged clauses, recoverable spend, and the negotiation email, exported as a branded PDF or a Markdown one-pager you can circulate.
The rule engine runs on every analysis, with or without an AI key. That's a design choice: the floor is deterministic, so a result never depends on a model being up.
Your data stays put
Stipula runs on your own machine, not our cloud, because there isn't one that ever sees your files. Your MSAs, vendor quotes, and spend exports are read where they sit. The analysis engine is fully local and works offline: no account, no upload, no third party holding your terms.
The deterministic engine runs the full analysis locally: no key, no connection required. Turn on the optional AI read and the document goes to your chosen provider, under your own API key, never through us, never stored on our side, never used to train a model. The floor is offline and yours; the ceiling is AI you opt into.
The name
Latin for a straw. Roman parties were said to seal a bargain by breaking a straw together, the origin ancient grammarians gave for the word stipulation. A promise, made physical. A term you could hold, and one you could break.
A promise, sealed.
We kept the idea and lost the ceremony. Stipula reads the terms you're about to be bound by, tells you which ones to break, and hands you the straw. Every term, on your terms.
Take the ledger with you
A branded overview (capabilities, the oilfield clauses we catch, and the real demo numbers), sized to forward to a colleague or drop into an AFE review. The same branded PDF the product exports on every analysis.
