What is Sequence?
Sequence is assembling the pieces for automatic invoice reconciliation, one at a time.
Sequence is billing and revenue infrastructure covering quotes, invoicing, payment collection and accounting sync. Recent releases converge on a single problem: knowing which money settled which invoice. Manual payments can now be recorded and settled on the ledger in one step, every payment shows whether it came from Stripe, GoCardless or manual entry, failed Stripe payments retry automatically, and selected invoices carry a running total.
What is Stigg?
Stigg adds credit reservation and settlement for AI operations days after its agent SDK.
Stigg can now reserve credits before an AI operation starts and settle the actual cost when it finishes. It follows the beta Agent Governance SDK, an open-source library built on Stigg's entitlements engine. Earlier October releases added an Airwallex billing backend, credit usage grouped by feature and a Stripe Projects listing.
Sequence vs Stigg: editorial side-by-side
Sequence
5.0FINANCE
Sequence is assembling the pieces for automatic invoice reconciliation, one at a time.
◆ Current state
Sequence is billing and revenue infrastructure covering quotes, invoicing, payment collection and accounting sync. Recent releases converge on a single problem: knowing which money settled which invoice. Manual payments can now be recorded and settled on the ledger in one step, every payment shows whether it came from Stripe, GoCardless or manual entry, failed Stripe payments retry automatically, and selected invoices carry a running total.
◆ Where it's heading
The reconciliation direction is stated rather than inferred — the manual payments release describes itself as a prerequisite for auto-reconciliation. Read together, the recent entries are that prerequisite list being cleared: capture every payment source, label its origin, retry the ones that fail, and total what remains. Alongside it, accounting-team control keeps surfacing, with Xero journal post mode giving finance teams a say in when recognition journals land.
◆ Prediction
Automatic reconciliation is the explicit next step, with payment origin labelling and manual payment capture both positioned as groundwork for it. Expect matching rules or suggested matches rather than another manual affordance.
Stigg
6.3FINANCE
Stigg adds credit reservation and settlement for AI operations days after its agent SDK.
◆ Current state
Stigg can now reserve credits before an AI operation starts and settle the actual cost when it finishes. It follows the beta Agent Governance SDK, an open-source library built on Stigg's entitlements engine. Earlier October releases added an Airwallex billing backend, credit usage grouped by feature and a Stripe Projects listing.
◆ Where it's heading
Credits have become Stigg's main pricing unit, and the product is adapting them to AI workloads whose cost isn't known up front. Reserve and settle, together with the governance SDK, turns the entitlements engine into a spending control for agents.
◆ Prediction
Expect the governance SDK to use reservations directly for agent limits, and more reporting on reserved versus settled usage.
