Small and medium enterprises remain central to Ghana’s economic development, yet many continue to experience profitability instability, weak liquidity control, poor record keeping, delayed receivables recovery, and limited access to formal finance. Financial management and profitability of SMEs in Ghana shows that working capital management, investment practices, and financial planning are central determinants of SME growth, with working capital management emerging as the strongest predictor of performance. Building on this evidence, this review examines digital working capital management as a contemporary pathway for improving cash flow resilience among Ghanaian SMEs operating within mobile money ecosystems. The paper focuses on how mobile money transactions, digital receivables tracking, automated payment records, real-time liquidity monitoring, supplier payment scheduling, mobile-based credit scoring, and data-driven cash conversion cycle analysis can strengthen SME financial stability. The review argues that digital financial tools can address long-standing operational weaknesses identified in Ghanaian SMEs, particularly dependence on mental records, poor separation of working capital from profit, inadequate accounting systems, and weak short-term debt management. The paper further evaluates how mobile money platforms can support cash inflow predictability, reduce transaction frictions, improve business traceability, enhance microcredit access, and strengthen financial decision-making among owner-managed enterprises. The review is theoretically anchored on contingency theory, trade-off theory, modern portfolio theory, and resource-based theory to explain how digital working capital systems interact with firm size, liquidity risk, financing structure, and managerial capability. The paper concludes that digital working capital management is not merely a payment innovation but a strategic financial resilience mechanism for Ghanaian SMEs. It recommends integrated mobile-money-based bookkeeping, digital cash flow dashboards, receivables automation, SME-specific credit analytics, and policy-supported digital financial literacy as critical interventions for improving cash flow resilience and sustainable profitability.
