Two follow-ups to the Services reorg that landed in 6d1816bd.
**Documents → Document** (singular). Documents/ was the only plural subdir in app/Services/ — every other bucket (Company, Mail, Module, Pdf, Storage, Update, ExchangeRate) was singular. Renaming to Document/ normalizes the whole tree.
**ExchangeRate → Integrations/ExchangeRate**. Introduces Integrations/ as an umbrella for external-service adapter subsystems. Exchange rate providers move in first; AI providers, payment gateways, and any other driver-pattern integrations land as sibling subdirs (Integrations/Ai/, Integrations/Payment/) without another reorg. Integrations/ was chosen over Providers/ to avoid conceptual collision with Laravel's app/Providers/ — 'check the providers' shouldn't be ambiguous.
17 files moved, 21 consumer files rewritten to point at the new namespaces via literal-string replacement (same approach as the previous reorg). 350 tests pass, Pint clean.
The app/Services/ directory had grown into 22 flat files at the root plus 7 uneven subdirectories — finding anything required scrolling through an alphabetical mix of small CRUD services, infrastructure drivers, and install-time utilities. This commit groups services by domain, folds Backup into a new Storage namespace, and moves framework-infrastructure and install-time helpers out of Services and into Support where they belong.
New Services layout: Documents/ (Invoice, Estimate, RecurringInvoice, Payment, Expense, Transaction, DocumentItem, SerialNumber, Currency — matches the 'Documents' navigation group); Company/ (Company, Member, Invitation); Mail/ (MailConfiguration, CompanyMailConfig); Storage/ (FileDisk, plus Backup folded in). ExchangeRateProviderService moves next to its drivers in ExchangeRate/; FontService moves into Pdf/ where it belongs. CustomerService, ItemService, CustomFieldService stay at the Services root as standalone single-file domains.
Moves to Support/: Hashids/ (library wrapper — not business logic); Setup/ (one-shot install-time utilities — stateless helpers); Pdf/ (ImageUtils, PdfTemplateUtils, plus the existing PdfHtmlSanitizer consolidated into the same subdir). These are all framework infrastructure and stateless utilities — the 'service' label never really fit them.
Namespace declarations in 29 moved files updated to match new paths. 62 consumer files (controllers, other services, tests, database factories, seeders, routes, bootstrap/providers.php) have their use statements rewritten via a literal-string replacement script — no regex meant no risk of half-matching. Three Documents services needed an explicit 'use App\Services\Mail\CompanyMailConfigService' added because the same-namespace short reference they relied on no longer resolves after the split.
Verified: composer dump-autoload, 350 tests pass (850 assertions), vendor/bin/pint clean, npm run build succeeds.
Merge InvoicePdfController, EstimatePdfController, PaymentPdfController
into DocumentPdfController with invoice(), estimate(), payment() methods.
Delete DownloadInvoicePdfController and DownloadPaymentPdfController
(dead code — not mapped in any routes).
Move DownloadReceiptController logic to ExpensesController::downloadReceipt()
(expense receipts, not PDF documents).
V1/Admin -> Company (company-scoped controllers)
V1/SuperAdmin -> Admin (platform-wide admin controllers)
V1/Customer -> CustomerPortal (customer-facing portal)
V1/Installation -> Setup (installation wizard)
V1/PDF -> Pdf (consistent casing)
V1/Modules -> Modules (drop V1 prefix)
V1/Webhook -> Webhook (drop V1 prefix)
The V1 prefix served no purpose - API versioning is in the route prefix
(/api/v1/), not the controller namespace. "Admin" was misleading for
company-scoped controllers. "SuperAdmin" is now simply "Admin" for
platform administration.
