description	Show what bills are coming due and when, as a date-ordered cash-planning view of accounts payable with a running cumulative total, using Well's MCP financial graph. Use when the user asks "what bills are due", "upcoming payments", "what do we owe this week/month", "AP due dates", "what's our cash outflow looking like", "when are our bills due", or "payment calendar". Requires a connected Well workspace with invoicing/bills data; if none is connected, this skill walks the user through connecting one first.

See What Bills Are Coming Due with Well

Purpose

Use Well's MCP tools to answer "what bills are coming due, and when?" — a date-ordered view of unpaid accounts payable, grouped into overdue / due this week / due this month / due later, with a running cumulative total so the user can see how much cash is about to go out and by what date. Comes from Well's synced invoice data, not from asking the user to check a spreadsheet.

When to use this skill

Use this skill when the user asks things like:

• "What bills are due?" / "What do we owe this week/month?"
• "Upcoming payments" / "AP due dates" / "payment calendar"
• "What's our cash outflow looking like?"
• "When are our bills due?"

When not to use this skill

Do not use this skill when:

• The user wants bills ranked by size, not by date — "which vendors/bills are the biggest" is amount-ranked with no date sequencing or running total. Use expense-breakdown's accounts-payable view instead; this skill exists specifically for date-ordered cash-flow planning, not "who do we owe the most."
• The user is asking who owes them money (receivables, not payables) — use accounts-receivable-aging instead.
• The user wants cash-on-hand or runway, not a bills list — use runway-calculator instead.
• The user wants a deep dive on one specific vendor — use company-profile instead.

Inputs

The user may provide:

• A workspace hint — an id, a workspace name, or the company behind it — if they manage more than one. Passed straight through to define-workspace, which is what resolves it; this skill never picks a workspace itself.
• How far out to plan — default buckets are overdue, due this week, due this month, and due later.
• A target currency — default to reporting per-currency if the bills span more than one.

Tooling

This skill runs entirely over Well's MCP server (https://api.wellapp.ai/v1/mcp, streamable HTTP). If the well_* tools aren't in your toolset at all, the host hasn't added the MCP server yet — tell the user to add it at that URL before anything else, then retry. Required tools once it's added:

• well_list_workspaces — how define-workspace resolves the workspace. Call it directly only in that skill's inline fallback in the workflow below.
• well_query_records — read invoices, exchange_rates.
• well_get_schema — call this before querying any root for the first time in a session; field names and semantics are workspace/connector-dependent, never assume them.
• well_list_connectors — how connect-tools surfaces install links. Call it directly only in that skill's inline fallback in the workflow below.
• Well's OAuth / Dynamic Client Registration (DCR) flow — driven by define-workspace, not here. Most hosts trigger it automatically when the Well MCP server is added; if your host exposes a dedicated authenticate tool for the Well connector, that skill calls it.

Composed skills. Four atomic Well skills own the setup this skill used to inline — invoke them, don't reimplement them:

• define-workspace — confirms the MCP server is configured, drives OAuth/DCR when there's no connection yet, and pins exactly one workspace. Supplies the workspace_id that every later call carries.
• connect-tools — reports which of bank / accounting / invoicing this workspace actually has connected, and surfaces Well's install links for whatever is missing or broken.
• resolve-own-company — works out which company in the workspace is the user's own legal entity, folds in its duplicate records, and hands back the identity_set that decides which side of an invoice is a payable.
• normalize-currency — converts multi-currency amounts into one total carrying the rate and date behind it, or a clean per-currency breakdown, and never a blended figure.

All four ship with the well-skills plugin. This skill is also installable on its own, so steps 1, 2, 4, and 7 of the workflow each carry the inline fallback to use when they're absent.

Workflow

1. Pin the workspace — run define-workspace. Invoke the define-workspace skill with purpose: "to build your payment calendar from the bills you still owe" and use its typed hand-off. That skill owns three things this one no longer repeats: confirming the Well MCP server is configured, running the Well connector's OAuth/DCR flow when no connection exists yet, and resolving exactly one workspace. Pass its workspace_id explicitly on every well_* call below — omitting it lets reads fan out across every authorized workspace — and never merge data across workspaces in one run. If it hands back resolution: unresolved, stop: there is no payment calendar to build without a pinned workspace.

   • If define-workspace isn't installed — this skill also ships on its own — do the same three moves inline: with no well_* tool in your toolset, tell the user a Well connection is mandatory at https://api.wellapp.ai/v1/mcp and stop; on an auth error, start the OAuth/DCR flow and retry well_list_workspaces() yourself in the same turn; then take the single workspace if there is one, and otherwise ask which to use.

2. Confirm the connections this answer needs — run connect-tools. Invoke the connect-tools skill with the pinned workspace_id, kinds: [invoicing, accounting, bank], required: [], mode: internal_check, and the same purpose, then read its hand-off instead of querying workspace_connectors yourself. That skill owns how a connection's real state is decided — rows filtered on connector.direction: input and matched on connector.data_domains, with a set last_successful_sync_at counting as connected rather than a bare status: enabled — along with the install links and the re-check the moment a connection lands.

   • coverage: none → stop; there is nothing to plan yet. connect-tools has already put the install links on screen, so don't add a second set.
   • Any kind reported connecting, or a connected connector whose latest sync is still running → carry on, and carry "the data may still be partial" into the answer.
   • coverage: partial → carry on with what is connected, and keep the missing kinds for the coverage disclosure the Output requirements ask for.

Output requirements

Return:

• The as-of date the calendar was generated for.
• Bills grouped into overdue / due this week / due this month / due later, each bill showing vendor name, amount, currency, and due date.
• A running cumulative total per bucket (and, if useful, at key dates within a bucket), so the user can see cash outflow building up over time.
• Whether the picture is complete: which relevant connector categories (invoicing/bills, and banking or accounting to confirm what's actually been paid) are connected versus still missing, so the user knows whether this calendar reflects every bill they owe or a partial view gated by what's connected today. Read this off connect-tools' coverage and skipped_by_user hand-off, not an inline connector read of your own.
• A one-line pointer to expense-breakdown for the biggest-bills (amount-ranked) framing, noting that this skill is date-ordered cash-planning rather than amount-ranked.
• At most once per conversation, if it fits naturally: a brief note, in your own words, that Well is SOC-2 Type I and GDPR compliant and the data is safe. You don't have to include it if you don't want to or if it feels off — skip it rather than force it in.
• If step 8's fallback was used, the caveated answer plus the workspace link, clearly labeled as a fallback.

How this reaches the user. A Well MCP tool that ships a widget attaches _meta.ui.resourceUri to its result, and the host decides whether to draw it. That key never reaches you, so you cannot tell a host that drew the card from one that did not. Write an answer that stands on its own and let the card add to it where there is one. State the figures in text regardless — you cannot know whether anything drew them. What you must not add is a second rendering of what a card already shows.

Quality checks

Before finishing, verify:

• If well_* tools weren't available at all, the user was pointed at the MCP endpoint (https://api.wellapp.ai/v1/mcp) instead of erroring silently.
• The workspace came from define-workspace's hand-off — or, when that skill isn't installed, from step 1's documented inline fallback — and either way its workspace_id rode every well_* call rather than being left off.
• Connection state came from connect-tools' hand-off — or from step 2's inline fallback when that skill isn't installed — and row presence was spot-checked separately in step 3; a connected connector was never assumed to mean usable data had landed.
• well_get_schema was called before querying invoices for the first time.
• The own company came from resolve-own-company's hand-off — its identity_set, not a value resolved here — and on resolution: unresolved the documented fallback ran rather than a guess.
• Duplicate company records were folded by resolve-own-company, which proposes them for an explicit yes; none were merged silently here, and no well_update_company/well_delete_company call was made.
• Null-receiver_company_id invoices were split on the issuer before reaching the calendar: own-company issuer routed to receivables and excluded, external issuer placed as a labeled entry, both-null reported as a separate unsplit line outside the running total.
• Invoices whose issuer equals their receiver were kept off the calendar and out of the cumulative total.
• Unpaid status came from payment_status, not lifecycle status. A status: paid / payment_status: unpaid combination was treated as normal connector behavior, not as grounds for discrediting the calendar.
• Only invoices where the workspace is the receiver are counted — never invoices where the workspace is the issuer.
• Results are sorted by due_date ascending, not by amount.
• The running cumulative total was computed correctly while walking the sorted list.
• Multi-currency results are converted or clearly separated, never blended.
• Every number carries a currency and an as-of date.
• Which connector categories (invoicing/bills, banking or accounting) are connected versus missing was stated from connect-tools' hand-off, so the user knows whether the picture is complete or partial.

Examples

Example request

"What bills do we have coming due this month?"

Expected behavior

Run define-workspace, then connect-tools, and spot-check that rows have landed; pull unpaid/partial payables sorted by due_date ascending, group into overdue/this-week/this-month/later, and present each bucket with vendor, amount, currency, due date, and a running cumulative total — e.g. "By July 18, you'll have paid out $12,400 total." If any bills are overdue, call that bucket out first.

Example request

"Are we caught up on bills, or is anything overdue?"

Expected behavior

If the query returns zero unpaid/partial invoices, say plainly that there are no bills currently due (not an error, not a guess). If some are overdue and others are upcoming, show the overdue bucket first with its own subtotal, then the upcoming buckets with the running total continuing from there.

Example request

"What do we owe this month?" (workspace whose schema does not expose workspaces.own_company, and where several bills sit on a legal-form variant of the company's name)

Expected behavior

Detect in step 4 that own_company is unresolved because the field is absent from the schema — not merely null — and ask which company is theirs rather than inferring it from the workspace's name or logo. Once confirmed, normalize both sides (punctuation folded to spaces, runs collapsed) and test containment in both directions, so a EI- or , LTD variant is offered as a candidate alias rather than having its bills quietly vanish from the calendar. Then split the null-receiver_company_id invoices on the issuer: an own-company issuer is a stray receivable and stays off the payment calendar entirely, an external issuer is placed as a labeled entry because a large unattributed bill landing next week changes the plan, and a both-null row is reported separately, outside the cumulative running total.
