Maritime Inventory Management System & Marine Stores

Marine stores management and inventory in one system

Tidal is a maritime inventory management system for marine stores management. Catalogue stores, spares and provisions on IMPA and ISSA codes, order against them, track stock levels, and keep a full history of every requisition and order, so buyers and suppliers always work from the same items.

Last updated: August 2026. Tidal now runs its maritime inventory management system across 43 ports worldwide.

Marine stores management lives or dies on consistent items. A vessel carries thousands of stores, spares and provisions, described a dozen different ways across suppliers and spreadsheets, so the same part is ordered twice, the wrong item is delivered, and no one has a clean history of what was bought. The problem is not effort, it is the lack of a single, coded item catalogue behind the ordering.

Tidal puts the catalogue at the centre. Items are matched to IMPA and ISSA codes so buyers and suppliers describe the same thing the same way; stores, spares and provisions are ordered against those coded items; stock levels are tracked as items are ordered and received; and every requisition and order is kept in a searchable history. The result is marine stores management that stays consistent from catalogue to order to delivery.

Marine inventory sits alongside the rest of your marine buying. It shares the catalogue and workflow behind our maritime procurement software and ship chandler software, and scales across vessels with fleet procurement software. See how the pieces fit across the Tidal platform.

Marine inventory management, answered

What is a maritime inventory management system?

A maritime inventory management system keeps a vessel's stores, spares and provisions on a single coded catalogue and manages ordering against it. Tidal matches items to IMPA and ISSA codes, orders stores and provisions against those items, tracks stock levels as they are ordered and received, and keeps a full order history, so marine stores management stays consistent.

How does Tidal handle marine stores management?

Tidal puts an IMPA and ISSA coded catalogue at the centre of ordering. Buyers requisition stores, spares and provisions against catalogued items, send RFQs to approved suppliers, and issue orders, while stock levels and a searchable order history are maintained automatically. Because everyone works from the same coded items, duplicate and wrong-item orders fall.

Does it track stock levels and order history?

Yes. Tidal tracks stock levels as items are ordered and received, and keeps a searchable history of every requisition and order. That makes it easy to see what is on hand, reorder recurring stores from past orders, and show finance and audit exactly what was bought and when.

How fast can we go live with Tidal?

Most customers are live within about a week. Tidal maps your stores catalogue to IMPA and ISSA codes, connects to your existing email inbox, and configures your suppliers and rules, with no IT project and nothing to install. You can start standalone and connect existing systems later.

How does the maritime inventory management system link inventory to RFQs and purchasing?
